OF THE PINE-APPLE.

I have been informed that, in both, the event 

 proved unsuccessful, and that the practice has 

 been discontinued. h 



It is natural to suppose that in a constant excess 

 of moisture, both in the tan-bed and bodv of the 

 stove, the Pine-plants would decrease in their 

 vigour, and their leaves soon become of a yellow 

 hue ; that the Vines would produce shoots weak 

 and long-jointed ; and that the bunches of grapes 

 would be constantly subjected to decay. How- 

 ever, by a moderate and judicious management, 

 the steam- pipe may prove advantageous to forcing- 

 houses in general ; and the method is simple and 

 easy. 



To the boiler, which is usually placed in the 

 back shed, a tube or pipe must be affixed, and 

 which must be conveyed through the . back wall 

 into the stove. From this tube or pipe, others of 

 smaller dimensions should branch out, and be con- 

 veyed in a horizontal position to any part of the 



h Although the method of conveying steam under the tan- 

 bed does not appear to answer for the culture of the Pine; still 

 it is very likely to prove an eligible expedient for forcing some 

 kinds of early vegetables, &c. that are less impatient of mois- 

 ture. — Thus we see cucumbers, melons, kidney-beans and 

 early potatoes (with many other articles in the line of forcing) 

 grow luxuriant, and flourish best in a hot-bed heat where there 

 is a constant and strong steam. Hence, this method may 

 prove advantageous to gardeners situate in places where early 

 vegetables sell at a high rate. On this consideration I shall 

 subjoin herewith a plan exhibiting the method of performing 

 this new mode of practice.
